I am toying with the idea of trying to roll one of these. I have a bit of experience with Arduino and Raspberry Pi. However, I need some suggestions on how to measure the amount of chlorine I am dispensing. One technique would be to use a small pump that has a flow rate I can measure, and simply tell it to operate for some number of seconds or minutes. I am wondering if anyone else has done this, and/or can suggest other ways to measure the amount of liquid being dispensed.

Yes, all you need is a Stenner pump and a timer. Search this site and you will find a lot of information and pictures.
wow. those pumps are expensive. would a smaller pump that dispenses in ml be large enough? I imagine I would want to dispense throughout the day, or over some period of time each 24 hour cycle.

Remember, that pump is outside, pumping product that is not real friendly. And you want it to be reliable.
It is actually more expensive than installing a real SWCG.

Stenner's are expensive because they can handle corrosive liquids like chlorine. Cheap pump would not last very long.
I found a good deal on the auction site for a Stenner, but eventually switched to SWG as its even easier than a Stenner.

With the cost of liquid chlorine (no end to price-increases seen) and the ease of a SWG, you may want to re-think your plan.
I've been running this pump for chlorine for over 2 years now with no problems. Amazon.com
I figured out how long it takes to pump 1 oz of chlorine and have a program that pumps 1 oz at a time however many times I need to get the dose I need. I split up the dose and put some in every hour but you could do it all at once.

I have two of them for acid and chlorine, each one is in one of the small boxes at the bottom.
A little peristaltic pump like the amazon link should be fine, the stenner is a bigger, AC version of that type of pump built to live outside.
This type of pump uses little rollers to move the liquid, so the pump itself is not exposed to Cl, just the tubing in the pump assembly is exposed.
Word of caution if you do this. Chlorine will cause deposits and gum things up over time, so you do need to disassemble and clean periodically, maybe once a year?
